Abstract

For the controlled lowering of a track (2), in a rear scanning location (11) of a measuring system (10) a longitudinal slope (α) of the track (2) is captured and recorded. For a length extending back at least (10) meters, a current height profile (16) is generated and a rear compensation line (17) overlaid thereon and representing a target track position is calculated. The rear scanning location (11) is computationally guided along the rear compensation line (17) such that a compensation value for the position of the measurement axis (12) results at a center scanning location (11) positioned between the rear and a front scanning location (11).

Description

Die Erfindung betrifft ein Verfahren sowie eine Maschine zur kontrollierten Absenkung eines Gleises gemäß den im jeweiligen Oberbegriff von Anspruch 1 bzw. 4 angeführten Merkmalen.The invention relates to a method and a machine for the controlled lowering of a track according to the features cited in the respective preamble of claim 1 and 4 respectively.

Eine derartige, als Gleisstabilisator bezeichnete Maschine ist durch US 5 172 637 bekannt. Das Messsystem weist drei auf dem Gleis abrollbare Meßachsen auf, denen jeweils ein Querpendel zur Erfassung der Querneigung des Gleises zugeordnet ist. Auf diese Weise ist die vor dem Maschineneinsatz vorliegenden Gleisquerneigung exakt kopierbar, so dass diese nach dem Maschineneinsatz unverändert ist.Such, referred to as track stabilizer machine is by US 5,172,637 known. The measuring system has three measuring axles that can be moved on the track, each of which is assigned a transverse pendulum for detecting the bank's lateral inclination. In this way, the track bank present in front of the machine insert can be copied exactly, so that it is unchanged after the machine has been used.

Gemäß GB 2 268 021 bzw. GB 2 268 529 ist es bekannt, in Verbindung mit einer Schotterreinigung zwei Längspendel je auf einem Fahrwerk anzuordnen, um vor der Entfernung des Schotters die Gleis-Istlage zu eruieren und diese nach der Einbringung des gereinigten Schotters wieder herzustellen.According to GB 2 268 021 respectively. GB 2 268 529 It is known to arrange in conjunction with a gravel cleaning two longitudinal pendulum ever on a chassis to determine the actual track before the removal of the ballast and restore them after the introduction of the cleaned ballast.

De 41 02 872 A offenbart ein gattungsgemäβes Verfahren sowie Maschine gemäβ den im jeweiligen Oberbegriff von Anspruch 1 bzw. 4 angeführten Merkmalen, und wird entsprechend als nächstliegender Stand der Technik angesehen.DE 41 02 872 A discloses a generic method and machine according to the features cited in the respective preamble of claims 1 and 4, respectively, and is accordingly considered to be the closest prior art.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens bzw. einer Maschine der eingangs genannten Art, mit dem bzw. der die Gleislage nach der Gleisabsenkung verbesserbar ist.The object of the present invention is now to provide a method or a machine of the type mentioned, with or the track position after the track lowering is improved.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren der gattungsgemäßen Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.This object is achieved by a method of the generic type by the features cited in the characterizing part of claim 1.

Das spezielle Problem von nach dem Einsatz des Stabilisationsaggregates vorliegenden Restfehlern liegt darin, dass diese im Laufe des Arbeitseinsatzes der Maschine zu einer immer größer werdenden negativen Beeinflussung der hinteren Abtaststelle führen können. Mit dem erfindungsgemäßen Verfahren ist es nun möglich, die hintere Abtaststelle des Messsystems entlang einer virtuellen Ausgleichsgeraden zu führen. Damit kann zuverlässig verhindert werden, dass die Genauigkeit des Messsystems in Verbindung mit der Gleisabsenkung mit Hilfe des Stabilisationsaggregates durch verbleibende Restfehler beeinträchtigt wird.The particular problem of residual errors present after the use of the stabilization unit is that they can lead to an ever-increasing negative influence on the rear sampling point in the course of the work of the machine. With the method according to the invention, it is now possible to guide the rear scanning point of the measuring system along a virtual straight line. This can reliably prevent the accuracy of the measuring system in connection with the track lowering is affected by remaining residual errors with the help of the stabilization unit.

Die genannte Aufgabe wird erfindungsgemäß auch mit einer Maschine der gattungsgemäßen Art durch die im Kennzeichen von Anspruch 4 angeführten Merkmale gelöst.The above object is achieved according to the invention with a machine of the generic type by the features cited in the characterizing part of claim 4.

Diese Ausbildung erfordert lediglich geringen konstruktiven Mehraufwand, ohne dass das Messsystem an sich verändert werden muss.This training requires only minor additional design effort, without the measuring system has to be changed in itself.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen:In the following the invention will be described with reference to an embodiment shown in the drawing. Show it:

Fig. 1 eine schematische Seitenansicht eines Gleisstabilisators mit einem Messsystem für eine kontrollierte Gleisabsenkung, Fig. 1 a schematic side view of a track stabilizer with a measuring system for a controlled track lowering,

Fig. 2 eine schematische Darstellung des Messsystems, und Fig. 2 a schematic representation of the measuring system, and

Fig. 3, 4 je eine weitere schematische Darstellung des Gleis-Höhenprofiles. Fig. 3, 4 each a further schematic representation of the track height profile.

Eine in Fig. 1 dargestellte Maschine 1 zu kontrollierten Absenkung eines Gleises 2 wird auch als Gleisstabilisator bezeichnet. Die Maschine 1 weist einen auf Schienenfahrwerken 3 abgestützten Maschinenrahmen 4 auf und ist mit Hilfe eines Motors 5 in einer Arbeitsrichtung 6 verfahrbar.An in Fig. 1 illustrated machine 1 for controlled lowering of a track 2 is also referred to as a track stabilizer. The machine 1 has a supported on rail chassis 3 machine frame 4 and is movable by means of a motor 5 in a working direction 6.

Zwischen den Schienenfahrwerken 3 befindet sich ein durch Antriebe 7 höhenverstellbares Stabilisationsaggregat 8 mit einem Vibrationsantrieb 9. Dieser erzeugt horizontal sowie normal zur Gleislängsrichtung auf das Gleis 2 wirkende Querschwingungen, die in Verbindung mit einer vertikalen Auflast durch die beiden Antriebe 7 eine Gleisabsenkung zur Folge haben.This is horizontally and normal to the track longitudinal direction acting on the track 2 transverse vibrations that have a track reduction in connection with a vertical load by the two drives 7 result.

Ein Messsystem 10 weist - bezüglich der Arbeitsrichtung 6 gesehen - eine vordere, eine hintere sowie eine dazwischen positionierte mittlere Abtaststelle 11 auf, die zur Abtastung der Gleishöhenlage jeweils auf dem Gleis 2 abrollbar sind. Zwischen vorderer und hinterer Abtaststelle 11 werden zwei in Maschinenlängsrichtung verlaufende Messsehnen 12 gespannt, deren Höhenlage bezüglich des Gleises 2 auf der mittleren Abtaststelle 11 abgetastet wird.A measuring system 10 has - seen with respect to the working direction 6 - on a front, a rear and an intermediately positioned middle scanning point 11, which can be unrolled on the track 2 for scanning the track height position. Between the front and rear scanning 11 two extending in the machine direction measuring jaws 12 are stretched, the altitude of which is sampled with respect to the track 2 on the middle scanning point 11.

Auf jedem Schienenfahrwerk 3 sind zwei Längspendel 15 angeordnet, die normal zur Maschinenlängsrichtung voneinander distanziert sind. Jedes Längspendel 15 dient zur Messung einer Längsneigung des Gleises 2. Für die Erfassung des zurückgelegten Weges ist auf der mittleren Abtaststelle 11 ein Wegmesser 13 vorgesehen. Eine Steuereinrichtung 14 dient zur Speicherung und Verarbeitung der durch das Messsystem 10 ermittelten Messwerte.On each rail chassis 3, two longitudinal pendulum 15 are arranged, which are distanced from each other normal to the machine longitudinal direction. Each longitudinal pendulum 15 is used to measure a longitudinal inclination of the track 2. For the detection of the distance traveled, a distance sensor 13 is provided on the middle sampling 11. A control device 14 serves to store and process the measured values determined by the measuring system 10.

In Fig. 2 ist das Messsystem 10 schematisch dargestellt. Die vordere Abtaststelle 11 wird auf einer durch eine Stopfmaschine korrigierten vorläufigen Gleislage geführt. Mit der im Bereich des Stabilisationsaggregates 8 positionierten mittleren Abtaststelle 11 wird eine Absenkung des Gleises 2 im Ausmaß eines vorgegebenen Setzmaßes h relativ zur Messsehne 12 erfasst. Die hintere Abtaststelle 11 wird entlang der endgültigen Gleislage geführt.In Fig. 2 the measuring system 10 is shown schematically. The front scanning point 11 is guided on a provisional track position corrected by a tamping machine. With the middle scanning point 11 positioned in the region of the stabilization unit 8, a lowering of the track 2 in the amount of a predetermined slump h relative to the measuring chord 12 is detected. The rear scanning point 11 is guided along the final track position.

Das bezüglich des Stabilisationsaggregates 8 (s. Fig. 1) bzw. der mittleren Abtaststele 11 hintere Längspendel 15 ist zur Erfassung der Längsneigung α des Gleises 2 vorgesehen. Die Steuereinrichtung 14 ist zur Abspeicherung der Längsneigung α sowie zur Bildung eines aktuellen Höhenprofiles 16 und zur rechnerischen Ermittlung einer das Höhenpröfil 16 überlagernden, eine Solllage wiedergebenden Ausgleichsgeraden 17 ausgebildet.With respect to the stabilization unit 8 (s. Fig. 1 ) or the middle Abtaststele 11 rear longitudinal pendulum 15 is provided for detecting the longitudinal inclination α of the track 2. The control device 14 is designed to store the longitudinal inclination α and to form a current height profile 16 and to computationally determine a Höhenpröfil 16 overlying, a desired position reproducing straight line compensation 17.

Sobald in der vorläufigen Gleislage - im Bereich der vorderen Abtaststelle 11 - durch Restfehler nach der Unterstopfung Ungenauigkeiten vorliegen, werden diese im Rahmen der Gleisabsenkung durch das Stabilisationsaggregat gleichsam kopiert. Die daraus resultierende besondere Problematik besteht nun darin, dass die hintere Abtaststelle 11 entlang dieser kopierten Höhenlagefehler (s. vollgezeichnete Linie in Fig. 2) geführt und damit die Genauigkeit der Gleisabsenkung noch zusätzlich verschlechtert wird.As soon as there are inaccuracies in the provisional track position - in the area of the front scanning point 11 - due to residual errors after the clogging, these are, as it were, copied by the stabilization unit as part of the track lowering. The resulting special problem consists in the fact that the rear scanning point 11 along this copied altitude error (see., Solid line in Fig. 2 ) and thus the accuracy of the track lowering is further deteriorated.

Um diesen gravierenden Nachteil zu eliminieren, wird mit dem hinteren Längspendel 15 (je nach Wahl der Bezugschiene das linke oder rechte Längspendel 15 des entsprechenden Schienenfahrwerkes 3) äquidistant (vorzugsweise in 20cm Abständen) eine Längsneigung α des Gleises 2 gemessen und in Verbindung mit einer Wegmessung durch den Wegmesser 13 in der Steuereinrichtung 14 abgespeichert.In order to eliminate this serious disadvantage, with the rear longitudinal pendulum 15 (depending on the choice of the reference rail, the left or right longitudinal pendulum 15 of the corresponding Schienenfahrwerkes 3) equidistant (preferably at 20cm intervals) a longitudinal inclination α of the track 2 measured and in conjunction with a displacement measurement stored by the odometer 13 in the control device 14.

Aus den abgespeicherten Werten für die Längsneigung α und die zugeordnete Wegmessung wird für eine von der hinteren Abtaststelle 11 bezüglich der Arbeitsrichtung 6 zurückreichende Gleislänge von wenigstens 10 Metern ein aktuelles Höhenprofil 16 des Gleises 2 gebildet. Anschließend wird rechnerisch die das Höhenprofil 16 überlagernde, eine Gleis-Solllage wiedergebende hintere Ausgleichsgerade 17 errechnet.From the stored values for the longitudinal inclination α and the associated path measurement, a current height profile 16 of the track 2 is formed for a track length of at least 10 meters that goes back from the rear scanning point 11 with respect to the working direction 6. Subsequently, the height profile 16 superimposed, a track target position reproducing rear equalizer 17 is calculated.

Die hintere Abtaststelle 11 wird rechnerisch entlang der virtuellen Ausgleichsgeraden 17 geführt, so dass sich an der mittleren Abtaststelle 11 ein entsprechender Kompensationswert für die rechnerische Position der Messsehne 12 ergibt. Diese Position ist für die Ermittlung des Setzmaßes h, das ist die aktuelle Höhe der Gleisabsenkung durch das Stabilisationsaggregat 8, maßgeblich.The rear scanning point 11 is mathematically guided along the virtual compensation straight line 17, so that at the middle scanning point 11 results in a corresponding compensation value for the computational position of the measuring chord 12. This position is decisive for determining the slump dimension h, which is the current height of the track lowering by the stabilization unit 8.

In Fig. 3 ist ein vorderes Höhenprofil 18 der vorläufigen, aus der Unterstopfung des Gleises 2 resultierenden Gleislage dargestellt. Dieses vordere Höhenprofil 18 ist durch von der Stopfmaschine aufgezeichnete und an die Steuereinrichtung 14 übergebene Messwerte bekannt. Sollte dies nicht der Fall sein, kann durch das am vorderen Schienenfahrwerk 3 vorgesehene Längspendel 15 und äquidistante Messungen das vordere Höhenprofil 18 abgetastet und abgespeichert werden. Über eine zurückreichende Länge von wenigstens 10 Metern wird rechnerisch eine vordere Ausgleichsgerade 19 gebildet. Entlang dieser wird rechnerisch die vordere Abtaststelle 11 geführt, um damit zu verhindern, dass die Restfehler auf das Messsystem 10 einen negativen Einfluss haben.In Fig. 3 is a front height profile 18 of the provisional, resulting from the clogging of the track 2 track position shown. This front height profile 18 is known from measured values recorded by the tamping machine and transmitted to the control device 14. If this is not the case, the front height profile 18 can be scanned and stored by means of the longitudinal shuttle 15 provided on the front rail chassis 3 and equidistant measurements. Over a length of at least 10 meters, a front straight line 19 is calculated. Along this, the front scanning point 11 is mathematically guided in order to prevent the residual errors on the measuring system 10 from having a negative influence.

Wie in Fig. 4 ersichtlich, wird für den Abschnitt a (Fig. 1) des Gleises 2 eine die Soll-Lage nach dem Einsatz des Stabilisationsaggregates 8 definierende, parallel zur vorderen Ausgleichsgeraden 19 verlaufende Soll-Gerade 20 gebildet. Die Differenz zwischen dieser und dem vorderen Höhenprofil 18 ergibt das jeweilige Setzmaß h für die Absenkung des Gleises 2. Um dieses unterschiedliche Setzmaß h zu realisieren, wird entweder die Frequenz für die Unwuchten des Vibrationsantriebes oder die Distanz der Unwucht relativ zur Rotationsachse verändert. Es wird somit eine an der mittleren Abtaststelle 11 ermittelte Differenz zwischen der Soll-Lage und der Ist-Lage des Gleises 2 als Regelgröße zur Änderung der dynamischen Schlagkraft verwendet.As in Fig. 4 can be seen, for the section a ( Fig. 1 ) of the track 2, a setpoint position after the use of the stabilization unit 8 defining, parallel to the front straight line 19 extending target straight line 20 is formed. The difference between this and the front height profile 18 gives the respective slump h for the lowering of the track 2. To this different Setzmaß to realize h, either the frequency for the imbalance of the vibration drive or the distance of the imbalance is changed relative to the axis of rotation. Thus, a difference determined between the desired position and the actual position of the track 2 at the middle scanning point 11 is used as the controlled variable for changing the dynamic impact force.
